What iVolt does

iVolt Limited is a UK-based designer and manufacturer of voltage optimisation equipment and LED lighting products, operating as a subsidiary of the Sollatek Group, which has nearly 35 years of experience in voltage stabilisation. Founded in May 2011 and headquartered in Slough, Berkshire, iVolt employs 11–50 staff and sells to enterprise customers across retail, education, healthcare, transportation, hospitality, leisure, government and manufacturing verticals in approximately 35 countries.

The company's core technology is a solid-state variable voltage optimisation system using microprocessor-controlled thyristor and transformer architecture, which reduces incoming UK mains voltage (averaging 242V) to an optimal 220V (±1.5%) — the level at which CE-marked equipment operates most efficiently. The proprietary Intelligent Real Time (IRT) Energy Monitor, built around a patented on-board algorithm, measures actual energy savings in real time, a capability iVolt claims is unique among voltage optimisation providers. The product family spans 63A–3000A capacities across four core SKUs (Commercial iVolt, Modular iVolt, Intellivolt HV/VO step-down, and Integrated iVolt/LV Panel). A second division offers a comprehensive LED lighting range covering street, interior, industrial, exterior and landscape applications, expanded from Sollatek's street lighting base in 2014–2015.

iVolt monetises primarily through direct enterprise hardware sales with custom pricing determined by site surveys and load profiles, supplemented by site survey, installation and energy audit services. The go-to-market model is consultative field sales targeting energy and facilities managers, augmented by channel partners RPP Energy Services Ltd (which project-managed the Morrisons rollout) and Bowers Electricals (Intellivolt HV/VO distribution), and public sector access via the ESPO procurement framework. A cloud-based monitoring portal introduced in 2017 enables multi-site remote management and real-time savings verification, positioning the company to evolve from discrete hardware sales toward connected installed-base services.

Core offering

iVolt designs and manufactures voltage optimisation units and LED lighting products for commercial, public sector and industrial customers. Its solid-state variable voltage optimisation units lower incoming UK mains voltage from an average of 242V to 220V, achieving energy and carbon savings of typically 4-20%, while its LED lighting range covers interior, exterior and street lighting applications.

Product overview

iVolt is a provider of energy saving and power quality technology products consisting of two main divisions: voltage optimisation and LED lighting. The voltage optimisation division offers four core products: Commercial iVolt (100A-3000A three-phase units), Modular iVolt (63A-100A compact stackable units), Intellivolt (HV/VO combined step-down transformer for 11kV to 380V), and Integrated iVolt/LV Panel (fully integrated VO/switch panel). All voltage optimisation products feature the proprietary IRT (Intelligent Real Time) Energy Monitor technology that measures actual savings in real-time, and are backed by nearly 35 years of voltage stabilisation expertise from parent company Sollatek. The LED lighting division, developed from Sollatek's 10+ years of street lighting experience, encompasses street lights (Standard and Lite ranges), interior luminaires (downlights, panels, linear lights, spotlights), industrial luminaires (high bay, low bay), exterior luminaires (battens, floodlights, landscape lights), and emergency lighting. Products are designed in the UK with global manufacturing.
